DUIVIPING-CART.

Specification of Letters Patent.

:Application filed/March 25, 1912.

Patented Ang. 26,1913. Serial No. 686,077.

T0 all 'wh-om t may concern Be it known that we, EVERETT R. JONES and THOMAS FITzrATnro/K, citizens Vof the Unit-ed States, residing at Kansas City, in' the county of Jackson, State of Missouri, have invented a new and useful Dumping- Cart, of which the following is a specification.

This invention relates to dum-ping carts particularly designed for carrying and dumping concrete.

The principal object of the invention is to provide a cart ofthattype having `a substantially cylindrical body mounted be,l

tween the supporting wheels of the vehicle, said body having spindles extending from the sides thereof and which are engaged by the supporting wheels, thus dispensing with the use of an axle such as is commonly employed and which extends entirely through the body.

Another object is to provide a body of this type which, when dumped, becomes completely reversed so that all of the contents thereof will be positively dropped therefrom.

A further object is to provide a body which does not require any special mechanism for inverting it to dump its contents.

Another ob] eet is to provide a simple form of lock for holding the body in upright position.

l.Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com` bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure l is a plan View of the cart. Fig. 2 is a side elevation thereof, the position of the body when dumping, being indicated by dotted lines. Fig. 3 is a central vertical longitudinal section through the cart. Fig. 4t is a central vertical transverse. section therethrough. Fig. 5 :is a side elevation, of one of the spindles and its attaching plate or casting.

Referring to the figures by characters of reference l designates side frame members connected at their rear ends by a cross memw ber 2. The side `members 1 converge forwardly as indicated at 3 and merge into thills 4 between which a draft animal may be placed. Another cross strip 5 is Vinterposed between and secured to the side members l close to the converging portions 3 and braces 6 may be interposed between this cross member 5 and said converging portions 3 as :indicated in Fig. l.

Journaled on the side members l are spindles 7 there fbeing bearing boxes S fastened on the side members and through which these lspindles extend. Supporting `wheels 9 engage the outer end portions of the spindles and the inner ends of these spindles are provided with attaching elements each of which is in the form of a casting made up of radiating lingers 10 adapted to be bolted, riveted or otherwise secured to one side of a substantially semi-cylindrical cart body l1. These spindles are so disposed at the sides of the body l1 that the greater bulk of the contents of the body will be located above the axis of rotation of the body ll. hen the body is in its normal or upright position, it is prevented from forward rotation by the front cross strip 5, as shown in Fig. 3 so that it is thus impossible for the body to dump its contents unless it rotates backwardly in the direction of the arrow in Fig.

An arm 12 is secured to one side of the body ll at the front thereof and is adapted, when the body is in its normal or upright position, to lie close to the outer face of one of the side members 1. A yoke 13 straddles this side member and is pivotally connected to it, this yoke having a handle 14. whereby it can be readily swung forwardly or rearwardly. Then the arm l2 is in its normal position, the yoke 13 can be swung rearwardly so as to straddle it and thus hold it against movement relative to the frame member 1. Obviously, therefore, the cart body will be prevented from dumping. By pulling forwardly on the yoke 13, however, the arm l2 will be released and, inasmuch as the greater portion of the weight of the contents of the body is located above the axis of rotation of said body, it will be apparent that the body will immediately swing backwardly and downwardly until it comes to the inverted position illustrated by dotted lines in Fig. 2. During this movement of the body all of its contents will be dumped th ere from.

Importance is attached to the fact t-hat the axle does not extend through the body. Such an arrangement has been objectionable because it leaves joints in the sides of the body through which thin cement may leak. Furthermore it interferes to an undesirable extent, with the discharge of concrete from the body.

It will be seen that When the body is moved to dumping position, the arm 12 comes forcibly against the cross member 2, thus bringing the body to a sudden stop and causing the positive ejection of any material which may adhere thereto.

lVhat is claimed is A dumping cart comprising a rectangular frame, a semi-cylindrical body rotatably mounted thereon With the axis thereof parallel to the longitudinal central axis of the frame and spaced a distance therefrom,

bea-rings rigidly secured to the upper portion of the sides of the said frame, spindles rigidly secured to said body and extending through said bearings, support-ing Wheels rotatably engaging sai spindles, an arm rigidly connected to one end of said body, means for engaging said arm for holding said body in an upright or normal position, said arm adapted to limit the rotation of said body, and adapted to bring the body to a sudden stop at said limit.

In testimony that We claim the foregoing as our own, We have hereto aflixed our signatures in the presence of two Witnesses.
